Obstacles #69

Closed ArndtTU closed 1 year ago

ArndtTU commented 2 years ago

Hello,

thank you for the simulator. I do have a problem though. Is it possible to create obstacles that interfere with the radio propagation such as buildings etc.? Especially in higher frequency ranges such as above 25GHz. I am using Simu5G v1.1.0 and don't think I can move to another version at this point. I am also using Veins ans SUMO and as far as I know do the buildings created with SUMO not hinder the radio propagation.

Thanks for your help!

Hello,

physical obstacles are not modelled within the simulator, and those created by SUMO are not considered. Channel models implemented within Simu5G follows 3GPP specifications, which I believe consider the complexity of the environment in some way. However, if you want to model physical obstacles accurately, you would need to implement a new channel model (or modify an existing one), so that it is aware of your "custom" objects in the environment. In other words, you would need a channel model whose mathematical model computes the power received by nodes by taking into account the presence of obstacles.
